One important item to design for is an increased structural load.
Green roof slope design.
Depth 3 5 13 of growing media visibility can be an architectural design feature.
To support the weight and handle the wear and tear from constant foot traffic the design team specified a beefed up version of a typical green roof system.
This is especially true of intensive green roofs which can have soil that is two feet deep or more.
0 5 roof angle green roof systems according fll without additional support.
There are a number of things to consider when designing for a green roof.
These systems are presented in the guide in relation to habitat water management energy needs and other factors affecting a project s design.
Green roofs are now feasible in sloped applications with hydrotech s gardnet option a growing media confinement component within the garden roof assembly.
Gardnet allows design professionals to expand beyond traditional flat roof applications and put a green roof in places they never could before.
Contact hydrotech for specific requirements.
It all comes down to the design as well as the types of plants that are added to the green roof.
Support a green roof.
Roof slope treatment volume is maximized on relatively flat roofs a slope of i to jr.
This means that you can have a green roof that s best suited for flat surfaces slanted roofs and more.
Green roofs can be installed on rooftops with slopes up to jmr if baffles grids or strips.
About 50 of the roof is at a 2 12 slope providing a fairly comfortable climb for visitors says blau.
Features of garden roof assembly for sloped applications.
5 15 roof angle systems with optional support depending on project.
1 4 estimate design installation and maintenance costs.
15 45 roof angle appropriate measures to cope with shear forces and erosion green wall.
1 9 determine type of green roof desired based on goals constraints and budget.
However some slope is needed to promote positive drainage and prevent ponding and or prolonged saturation of the growing media.
Plants that are used often with this treatment are ones that are tolerant to droughts including certain sedums succulents a few types of grass and mosses.
Usually mosses succulents bulbs and tubers grasses herbs herbaceous and woody plants are recommend for green roofs.
Any large slope or flat roof that s hard to reach makes a great area for this kind of vegetation as nature will take care of itself.

A green roof system is perfect for over the garage for example and it can be integrated into almost any architecture style.
